Eczema, extremely dry skin!!

Hi, I posted on here a few months back with concerns about my skin. I was told to ask my doctor for a referral to a dermatologist, which I did. However he told me that doctors are pretty much dermatologists too, so there was no need. I was just given various shampoos and shower creams, none of which really helped.

I'm 16, suffered eczema all my life. I use Epaderm every day, every morning i have to use it on my entire upper body and face before dressing.I wouldn't actually mind this too much if my skin didn't start flaking halfway through the day. By night time it's flaking quite a bit and is dry and tight. This is such an annoyance like, if I'm to say go out at night etc, I really don't have time to be undressing just to moisturise all over again. I'm just really sick of it. Changing my diet doesn't help, either.

The one and only cream I have used that kept my skin amazingly soft, was Neutrogena. Unfortunately it's really expensive and I just don't have the money. I was wondering if anyone knew of any other really good creams like that? I've also tried Diprobase which was even worse than epaderm.. I've tried body butters from body shop, again didn't do much good, also tried all sorts of in shower moisturisers which if anything made my skin drier.Sorry for such a long post, thanks!
